Universal relation with regime transition for sediment transport in fine-grained rivers
(National Academy of Sciences, 2019-12-18)
Fine-grained sediment (grain size under 2,000 μm) builds floodplains and deltas, and shapes the coastlines where much of humanity lives. However, a universal, physically based predictor of sediment flux for fine-grained ...
Development of a scalable procedure by a discontinuous crossflow DF/UF to obtain a concentrate of chenopodin from a dead-end centrifugal UF at bench scale
(Elsevier, 2020)
The aim of this study was to develop a scalable crossflow diafiltration/ultrafiltration procedure for quinoa 11S globulin purification starting at the bench scale using Ultra15 centrifugal filter devices. The electrophoretic ...

Assessment of landslide occurrences in Serra do Mar mountain range using kinematic analyses
(2018-05-01)
Due to its meteorological, geological and geomorphological settings, Brazilian’s Atlantic coast have suffered severe landslide phenomena, particularly along the cost of São Paulo, Rio de Janeiro, and Santa Catarina states. ...
Aspectos computacionais da formulação variacional ultra fraca aplicada ao eletromagnetismo
(Universidade Federal de Minas GeraisUFMG, 2017-03-17)
Numerical methods that use plane waves as basis functions to approximate the solution of the Helmholtz equation have received considerable attention in computational electromagnetics. These approaches do not require the ...
Discontinuous Galerkin spectral element method to compute reflection and transmission of electromagnetic wavesMétodo de elementos espectrales de Galerkin discontinuo para calcular reflexión y transmisión de ondas electromagnéticas
(Universidad de Costa Rica, Centro de Investigación en Matemática Pura y Aplicada (CIMPA), 2018)
A LDG-BEM COUPLING FOR A CLASS OF NONLINEAR EXTERIOR TRANSMISSION PROBLEMS
(SPRINGER, 2006)
We consider the coupling of local discontinuous Galerkin (LDG) and boundary element methods (BEM) for a class of nonlinear exterior transmission boundary value problems in the plane. We introduce suitable numerical fluxes ...
MATHEMATICAL MODELS FOR THE SEDIMENTATION OF SUSPENSIONS
(SPRINGER, 2006)
Mathematical models for sedimentation processes are needed in numerous industrial applications for the description, simulation, design and control of solid-liquid separation processes of suspensions. The first simple but ...
